This puzzle:

Now that there were blogs, and I had attended the ACPT two years in a
row, I now had lots of friends in the crossworld. One of them is
Ashish Vengsarkar. We decided to collaborate on an idea I had of lots
of fishing terms that were used as metaphors in other situations.
Ashish constructed the grid and added MARINEGREEN and UNDERTHESEA as
long downs. We disagreed about that.
I like all the themes to be horizontal (I don't think I've ever had
theme answers running down and I didn't want ones that were sort of
like the theme but not really).
Ashish hung tight and as it was a collaboration, I eventually deferred
to him. He proved right in that folks loved the extra "atmospheric"
entries.

Even tho solvers love long answers, I think if they are as long as the
theme answers, that is really confusing. But I do like having bonus
and atmospheric words in the grid to add to the overall feel.
